3 Claims. (Cl. 22929) The present invention relates to egg cartons and the like, and has for its object to improve the same.

Regarded in its most specific aspect, the prescut invention may be to have for its object to improve the carton disclosed in Patent No. 1,430,617, granted to Peter Berke'y, on October 3, 1922. The carton of that patent is composed of two separate blanks, a body blank and a cenlo tral longitudinal partition element. The body blank is cut, folded and glued to produce front, rear and bottom walls, a cover, and transverse partitions hinged at the top to the tops of the front and rear walls. The transverse partitions,

15 in setting up the carton, are swung down at right angles to the bottom wall, and the central longitudinal partition is then interlocked with the transverse partitions, the transverse partitions having at the middle notches extending downwardly from the upper edges, and the longitudinal partition having notches extending up from the bottom edge, to permit the partitions to be interengaged and allow the transverse partitions to rest on the bottom wall of the carton, along the longitudinal center.

In accordance with my invention, 1 so modify this carton that the longitudinal partition is inserted from below. In carrying out this thought, I change the bottom wall from a fiat condition to a wall sloping downwardly toward the front and rear walls from a central longitudinal ridge. In other words, the bottom wall, in end elevation, takes the shape of a flattened inverted V. The longitud nal partition is so shaped that the lower longitudinal portion is in the form of a continuous strip of a height preferably about equal to the distance of the ridge in the bottom wall above the plane of the extreme bottom of the carton; whereby this strip forms a positive support so for the bottom wall along the longitudinal center. Consequently, the bottom wall consists of two oppositely sloping sections each supported at its two long edges when the carton isresting on a flat surface, and being clear of any support from below at all points between said edges. By this means, when eggs are placed in the carton, they rest on the slopes of the bottom wall and cannot strike against a fiat surface on which the carton may be resting, and they are, there- .go fore, protected against breakage due to dropping the carton or setting it sharply down on a hard surface. s

The various features of novelty whereby my invention is characterized will hereinafter be pointed out with particularity in the claims; but,

for a full understanding of my invention and of its objects and advantages, reference may be had to the following detailed description taken in connection with the accompanying drawing, wherein:

Figure 1 is a perspective view of one of my improved cartons, set up ready for use, the cover being shown open; and Fig. 2 is a central vertical longitudinal section through the carton, with the cover closed, a section of the carton between the ends being omitted.

The carton shown in the drawing consists of a body member having upright front and rear walls 1 and 2, a bottom wall which, when fiattened'is Wider than the Width of the completed carton, a cover 3 constituting an upward extension or" the rear wall 2, a locking flange 4 on the cover, and a series of transverse partitions 5, each connected at one upper corner to the top of the front wall by a triangular gusset 6 and to an attaching strip '7 at the opposite upper corner by a similar gusset 8. The strip 7 is glued to the rear wall and, to place the carton in condition for use, the transverse partitions are swung down, as shown in the drawing, and the longitudinal partition, to be so hereinafter described, is inserted.

The bottom, wall, being wider than the completed carton, is folded along the longitudinal center line so as to produce two sections 9 and 10, sloping downwardly in opposite directions from the longitudinal center to the rear and front walls, respectively. Those ends of the transverse partitions that are at the bottom, when a carton is set up, are preferably shaped, as indicated at 11, to fit againstthe slopes 9 and 10. Furthermore, each transverse partition has at the middle, between the top and the bottom, a slot 12 which is wholly surrounded by the material of the par tition.

The central longitudinal partition consists of a long strip, 13 which preferably has a width equal to the height of the V into which the bottom wall is shaped so that, when the strip is set in the angle of this V and the carton is resting'on a fiat surface, the strip forms a support for the bottom wall, along the longitudinal center of the carton. The bottom wall of the carton is provided with a series of slots 14, extending lengthwise thereof along the ridge of the bottom wall; there being as many of these slotsas there are transverse partitions, and each slot terminating at one end adjacent to the lower end of the corresponding transverse partition, when the latter is swung down at right angles to the bottom; Rising from the strip 13 are a series of elements or wings i5, no

narrow enough to pass through the slots 14, and so shaped that the base portions thereof adjacent to the strip will substantially fill these slots. The elements 15 are preferably high enough to reach up to the cover of the carton when the cover is closed, and thus constitute supports for the cover along the longitudinal center line. Each of the elements 15 is also provided with a triangular edge projection or nose -16 in position to pass through the slot in the corresponding transverse partition and thus interlock the longitudinal partition with the transverse partitions.

It will thus be seen that, without changing the manner of manufacturing the old type of twopiece carton, I have produced a carton which possesses a cushion bottom or, at least, a bottom which efiectively holds the eggs well-above a flat surface on which the carton may be resting and thus protect the eggs.

While I have illustrated and described with particularity only a single preferred form of my invention, I do not desire to be limited to the exact structural details thus illustrated and described; but intend to cover all forms and arrangements which come within the definitions of my invention constituting the appended claims.

I claim:

1. In a carton, a body member composed of front, rear and bottom walls; and transverse partitions; the bottom wall having central longitudinal slots; and a central longitudinal partition comprising a continuous narrow strip-like section underlying the bottom wall and elements rising therefrom through the slots in the bottom wall; said elements and said transverse partitions having shoulders interlocked with each other to hold the longitudinal partition against withdrawal in the downward direction.

2. In a carton, a body member composed of front, rear and bottom walls, and slotted transverse partitions, the bottom wall having central longitudinal slots and being bent inwardly of the carton defining a central longitudinally extending ridge and portions sloping downwardly therefrom to the front and rear walls, and a central partition underlying and supporting the bottom wall beneath the ridge and having integral members rising through the slots in the bottom wall, the edges of said integral members defining shoulders interlocked with the slotted transverse partitions to hold the central longitudinal partition in its position of support.

3. In a carton of the type described, a body member composed of front and rear walls, transverse partitions, a bottom wall being bent inwardly of the carton defining a central longitudinally extending ridge and portions sloping downwardly therefrom to the front and rear walls and having longitudinal slots along said ridge,

and a separate longitudinal partition underlying said bottom wall beneath the longitudinally extending ridge and having integral members protruding upwardly through the slots in the bottom wall, said members having means for engagement with the transverse partitions and being spaced from each other at their upper edges to form openings for receiving said transverse partitions when said members are pressed upwardly through the slots in the bottom wall.

FELIX TROYK.
